Alternative syntax for "install" command?

Hyperscript's behaviors are a wonderful thing, but instantiating them on an element always reads a little funny. @dz4k has promoted `I am` as an alias for the `install` command, as in ``. While this reads wonderfully, it could certainly be trouble for the parser. Here are two alternatives to consider:

## "Use"
We're not currently using the keyword `use`, and it seems to fit semantically, as in:

```

```

## Distinct Attribute
Since this is such a DOM-speciic feature, it might work well to separate it into its own attribute -- something like:
```

```
or even
```

```

Thoughts?
